FOOT-POWER HAMMER.

Specification of Letters Patent.

Patented Sept. 12, 1905.

To (LIZ Vw'lm'mj it 'nm/y concern.'

Be it known that we, GEORGE E. 'VILLrAus and AURA M. VVILLiAMs, citizens of the United States, residing at Bartlett, in the county of Labette, State of Kansas, have invented certain new and useful Improvements in Foot- Fewer Hammers; and we do hereby declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to foot-power harniners; and it has for its object to provide a construction wherein the blow of the hammer may be accomplished by the pressure of a foot-lever and in which the hammer may be swung laterally to strike upon different portions of the face of an anvil.

A further object of the invention is to provide a construction which will permit of vertical adjustment of the hammer to suit different conditions of operation and in which, furthermore, the head of the hammer may be adjusted so that its face may be in proper relation to the work when the blow is struck.

Other objects and advantages of the invention will be understood from the following description.

ln the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure l is a side elevation of the hammer, the near side of the upright frame being broken away. Fig. 2 is a rear elevation of the apparatus. Fig. 3 is an elevation of a front or the portion adjacent to the anvil. Fig. el: is a top plan view. Fig. 5 is a vertical section through the machine in the common plane of the mast and the hammer-handle. Fig. 6 is a horizontal section through the mast just above the lower clutch. Fig. 7 is a horizontal section through the hammerhead and a part of the handle thereof.

)teferring now to the drawings, the present apparatus comprises a base-frame including sills 10 and 11, at the ends of which are the cross-pieces 1Q and 13, and within the inclosure of one end of this frame is secured the block 1-1, upon which is mounted the anvil 15, which latter extends transversely of the frame.

Upon the sills 10 and 11 are mounted the arches 16 and 17, against the outer side faces of which are secured the bifurcated lower ends of the sides 18 and 19 of an arched frame, the top Q0 of which is Ilat. The arches 16 and 17 are connected by the cross-piece Q1, in which is rotatablyY mounted a mast 22, which engages rotatably a perforation 23 in the top 2O of the arch-frame. The mast is continued above the arched frame, and upon its upper end is mounted a yoke-,plate 24, the free ends of which are bent outwardly in opposite directions and have mounted thereon the pillow-blocks 25 and Q6, in which is journaled a rock-shaft 27. The yoke-plate is held upon the Lipper end of the mast by means of the nut 25, engaged with the reduced upper end of the shaft and holdingI the yoke-plate upon the shoulder at the base of its reduced portion of the mast. The rock-shaft carries a transverse seat Q8, in which is disposed the handle 29 of a hammer, the handle being' held in the seat by means of clips BO, which when loosened permit of adjustment of the handle longitudinally of the seat, so that the head of the hammer may be in proper position in relation to the face of the anvil.

The rock-shaft is held normally and yieldably with the halnmer-hezul raised from the anvil by means of a helical spring 31, which is attached at one end to a crank -arln 32 at one end of the rock-shaft, while its opposite end is connected to a turnbuckle 33, which is connected in turn to an arm Bet, which projects from the side of the mast.

Upon the sills l0 and 11 are mounted pillow-blocks 35 and 36, in which is disposed a rock-shaft 37, on which is fixed a block 38, having the spaced cars 39, between which is pivoted the downwardlyturned end of a treadle 40, the opposite end of which operates in a guide 41, secured to the side of the anvil base or block.

The shaft 27 carries a peripherally-grooved segment L11, at one end of which groove is attached a chain 42, which lies in the groove and passes from the opposite end thereof adjacent to the anvil downwardly between the anvil and the arched frame, where it is connected to a turnbuckle 3, which is also connected with the treadle. lVhen the treadle is depressed, the chain is pulled downwardly, so that the segment is rotated and the shaft 27 is rocked to swing the hammer-head down upon thefacc of the anvil. Vhen the treadle is released, the helical spring moves the rock- IOO shaft 27 in the opposite direction, so that the hammer is raised from the anvil.

By reason of the rotary movement permitted the mast, the hammer may be swung with its head laterally to strike different parts of the anvil, the mast being shifted rotatably by means of the handle 44, one end of which is pivoted between the ears of a clip 45, secured to the mast above the arched frame. The mast is also slidable vertically in its bearings to raise and lower the hammer, and to hold the mast at different points of its vertical adjustment a collar 48 is mounted upon the mast and rests upon the cross-piece 21. The collar is split, as illustrated, and between the ears 48 at the ends of the collar is pivoted a cam clutch-lever 49, which is movable into and out of engagement with the mast, the shape of the cam and the location of its pivot being such that the Weight of the mast and the parts carried thereby will serve to rotate the cam into more intimate contact with the mast. The active position of the clutch-lever is maintained by means of a hook 50, which is slidably mounted upon the mast and is rotatable also thereon to engage and disengage the lever. The lever is .curved as illustrated, so that it diverges downwardly from the mast, and by sliding the hook downwardly of the mast and lever the lever is drawn toward the mast to press the cam more firmly against the mast. The split collar is provided With a laterally-directed lug or flange 52, which is perforated to receive a pin 53 in connection with a perforation 54 in the cross-piece 2l when it is desired to hold the mast against rotation. To hold the mast against upward movement when the hammer strikes the anvil or work thereon, a second collar 55 is mounted on the shaft directly below the top of the arched frame. The upper collar is split, and between the ends thereof'is pivoted the cam-shaped end of a second clutch-lever 56,the'

opposite end of which is swung downwardly to engage the cam with the mast. rlhe lever is held in active position by means of the hook 57, which is mounted slidably and rotatably on the mast, so that it may be swung into and out of engagement with the lever and also adjusted to different points of the length of the lever to hold the latter with diii'erent pressures in active positions, it being noted that the lever is curved longitudinally. The upper split collar is held against rotation by means of a pin 59, engaged with the flange 'thereof and with the top of the arched frame. Vith this construction it will be seen that the mast may be held securely against vertical movement at any point of its vertical adjustment and that by releasing the upper clutch-lever and withdrawing the pin from the lower split collar or clutch-ring the mast may be rotated to swing the hammer at different points of the vertical adjustment of the mast.

It will of course be understood that it is desirable to hold the face of the hammer-head in different positions or at dierent angles to the face of the anvil under different working conditions, and for this purpose the head 61 of the hammer is pivoted to the handle Q9 for movement in a vertical plane longitudinally of the handle. The handle adjacent to the head is screw-threaded, as shown at 62,' and engaged with this threaded portion is a nut 63, which is grooved pcripherally to receive a strap 64, to which are pivoted the ends of a bifurcated brace 65, which is pivoted also in the upper portion of the inner face of a hammer-head. By adjusting the nut on the handle the brace is shifted to swing the hammer-head pivotally, the nut serving also, in connection with the brace, to hold the head securely in its adjusted positions.

It will be understood that in practice modifications of the specific construction shown may be made, and any suitable materials and proportions maybe used for the various parts without departing from the spirit of the invention.

That is claimed isl. An apparatusof the class described cornprising a rotatable and vertically-adjustable mast, a pivoted hammer carried by the mast, separate means for holding the mast against vertical movement in opposite directions and means cooperating with one of said holding means for holding the mast against rotation.
